The volume of a steady-state crystallizer is 85,000 L, and the solids fraction in the unit and the exiting stream is 0.35; that is, there are 0.35 kg of crystals per kg of slurry (the crystal-solution mixture). The density of the solution is 1.1 g/mL and that of the crystals is 2.3 g/mL. The production rate of crystals from the crystallizer is 19.5 kg crystals/min. Estimate the volumetric flow rate of slurry from the crystallizer and the drawdown time of the crystallizer (the time it would take to empty the crystallizer if the feed were discontinued).
